PIRANHA SCHOOL

[Merlin Aldous Espinoza]

What type of piranha can go to school? I mean swim together, not bitting a fellow snapper or other fish inside the tank.

[Snake_Eyes]

Any of the Pygocentrus genus...Nattereri, Ternetzi, Piraya, Caribe. There is still a risk of aggression and cannibalization though mainly with piraya and caribe.

I second what snake said.
Piranha will not school or "shoal" like some ocean schooling fish swimming in synchrony. They group together and tolerate eachother. Any member that has kept a group of pygo's for any length of time will tell you that aggression towards tankmates is always a constant threat. I don't care if you have two pygos or 20. A 10 gallon tank or a 1000. These fish have razor's for teeth so problems are never pretty. Most of the time its a tail nip that grows back quickly...Sometimes its not.

pirhana will have no long term roomates, just when you think they are all buddies you turn out the lights one night and they are eaten

[vlahos]

pygo species are schooling fish, and so are p. denticulats
since piranhas as a whole are aggressive fish, there is always a risk of cannibalism and fish dying within the school.
if properly fed and the tank is sufficient size (20-30g per fish) then usually problems are avoided

[ronnie]

i agree with all the statements above


hehehe

I have 5 Red Bellies that are about 4 to 5 inches. They are constantly nipping and chasing each other around. Just a couple days ago I woke up and one of them has a dime size chunk of skin and flesh missing from his side. I think that is just part of owning Piranha.

[amurray]

U can also school exodons, wimples, and denticulatus
U can get them on aquascapeonline.com:headbang2
but wimples are probably the least aggressive piranha and only grow to about 4-6inches

Piranha will be Piranha. One month they are all swimming happily and the next morning one of your prized fish is just a head at the bottom of the tank.

You take your chances with such an aggressive fish.

exactly.

as for the 20-30g rule i never adhered to that espceially with bigger tanks.

Hi, my name is norma, I have had 4 redbellies and i only have two now. They ate eachother. And the two that i have right now are missing part of their noses. Can they go with oscars? They are big already.

[sirasoni]

anything you put in there is a gamble.

[monty_javier]

i have a buddy who has seven red bellies in a 55 gal. other than the normal nip and tail loss he hasnt really had to much problem with them.

[PirhanaMan]

I've had two Tigershovelnoses in a tank with 8 Redbellies for almost 8 months now.. From my experiences.. you can keep Redbellies with some other tankmates depending on how well fed they are, what the food sources are,.. and of course the kind of tankmates is the biggest variable.. Fish that are very active will attract the attention of your pirhana.. and then suffer the capitol punishment.. hehe

[PirhanaMan]

I have had in the past black P's.. nothing lives with those guys.. nothing

[Pfisherman]

Oscars and P's go together like acids and bases, the same thing with only having to Ps.

You should never have only to Ps as there is nothing to dilut the agression, 1 p okay, 3-one million Ps okay, 2ps no good.

anyway piranah of the pygocentrus genre are loose shoaling at best, they will always batlle over food, dominance, territroy, mates and just plain nipping. dont besurprised when one gets wounded in battle, after all every one knows the old saying, it all fun and games till someone loses an eye. which is not all a to uncommon in a shoal of ps
